WATER-COOLING RADIATOR FOR USE IN HEAVY VEHICLES.

Application filed June 5, 1925, Serial No. 35,226, and in Germany June 7, 19 24.

The invention relates to a radiator for cooling the cooling water of the internal combustion engines in heavy vehicles and especially in locomotives. For removing the great amount of heat becoming free in such engines it is known to use special cars with coolers and ventilators, and also it is known to guide the heated air from the cooler into an upward direction.

The invention specifically consists in a water cooling radiator for heavy vehicles comprising, in combination, a cooling block or body constructed of heat transmitting walls for arrangement on the front of the vehicle, lateral cooling blocks ar anged near said front cooling block, an upwardly directed chimney, curved guiding walls connecting said blocks to said chimney so as to adjoin proportional areas of said chimney to proportional areas of said cooling blocks, and a suckin ventilator in said chimney as hereinafter described and claimed.

In the drawings Figure 1 is a vertical sectional view of a water cooled radiator constructed and arranged in accordance with my invention, on the line I-I of Figure 2.

Figure 2 is a horizontal sectional View of the same on the plane indicated by the line IIII of Figure 1.

In accordance with this invention the main part of the cooler consists of a cooling block 1 constructed of heat transmitting walls for arrangement on the front of the vehicle, and lateral cooling blocks 2 near said cooling block 1, each of the cooling blocks being provided with vertically or nearly vertically arranged tubes, as indicated in Figure 2, which contain the cooling water.

In the middle between these cooler blocks an exhaust chimney 3 with 'a ventilator 4 is provided. The chimney 3 is quadrangular on its bottom part and circular near the ventilator. The front cooler 1 is connected to said chimney by two vertical walls 5 approaching to each other in triangular shape and united by a bottom wall 6. Each lateral cooler 2 is similarly connected to said chimney by one of the walls 5 and a further wall 7, and these channels are closed by bottom walls 8. The cross area thus separated in the chimney 3 have the same relation to each other as the air current cross sections of the coolers 1 and 2.

Further from the front cooler 1 guiding walls 9 are led to the chimney 3 so that equal areas of the chimney correspond to equal areas of the cooler air cross section.

Spaced vertical walls 1.0 connect the walls 5 with the rear walls of the chimney, as shown in Figure 2. In the operation of the invention the air which is caused to pass up through the chimney 3 by the rotation of the ventilator or fan 4c cools the water in the tubes of the blocks 1, 2 by passing between said tubes and is deflected upwardly between curved upwardly extending walls 9 and is forced upwardly with such velocity as to prevent the formation of whirls and eddies in the'cin'rent. Hence all hotair which arises from the internal combustion engine, in connection with which the apparatus is used, is effectively carried off. The apparatus is effective even in very hot climates and is operative at comparatively low power consump tion. I

I claim:

1. A water cooling radiator for use in heavy vehicles, comprising in combination a cooling block constructed of heat transmitting Walls for arrangement on the front of the vehicle, lateral cooling blocks arranged near said first cooling block, an upward directed chimney, curved guiding walls connecting said blocks to said chimney so as to join proportional areas of said chimney to proportional areas of said cooling blocks, and a sucking ventilator in said chimney.

2. A water cooling radiator for use in heavy vehicles, comprising in combination a cooling block constructed of heat transmitting walls for arrangement on the front of the vehicle, lateral cooling blocks arranged near said first cooling block, an upward directed chimney, a series of curved guiding walls connecting several parts of every one of said blocks to proportional parts of the cross area of said chimney, and a sucking ventilator in said chimney.

In witness whereof I affix my signature.
